The divs which needs to have shadow applied has a common class. In the fiddle it is test.
I have created a fiddle

It should work on IE8 and above and so I guess CSS3 can be used.

Question 1 : If i do something like fork, it updates both the dumping of data simultaneously right? i.e. if parent process is getting data from source A and dumping in Object O, and chil process is getting from B and dumping in Object O only, the O gets populated simultaneously right? It will not create two objects one with data from A and other with data from B. Also, the efficiency of this process lies in the multiprocessor systems only?

To note, I load additional content when reaching the bottom of the scroll.
scrolling down with one move;

To note, I load additional content when reaching the bottom of the scroll.
scrolling down with one move;
> image: http://puu.sh/Ng05.jpg
touching the bottom of the screen - the content only now appears;
> image: http://puu.sh/Ng0F.jpg
Other than that, sometimes the scroll also gets quite buggy, e.g. it jumps up/down when touching the content.
Thanks! | 0 |

I have configured the Datatable to use ajax search and sort routines, and I am using an extension method to allow me to specify the name of a column to be sorted as a string. This works perfectly for most fields, but I get an error when trying to sort a field that contains a DateTime object.

show:true,
location:'s',
fontSize: '1em',
centerLabel: true, // extra option, see code

**According to my knowledge(very less) I have some suggestion:**
**For Point1:** By Hard-coding my application's startUp to check for the ProcessorId(because it is unique one) If it is a valid one it should execute else show a "Expired" alert. But for doing this i should give a separate jar setUp to each user which i dont mind.
**For Point2:** Should maintain a encrypted file which will store the current date. During each startup of the application. I will update the date field in the file if the current date is greater than the one in the file. If not i will display a "Expired" alert.
This may look funny but this is what I can think.

$.fn.serializeObject = function() {
var arrayData, objectData;
arrayData = this.serializeArray();
objectData = {};
$.each(arrayData, function() {
var value;
if (this.value != null && this.value != '') {

value = null;

}
objectData[this.name].push(value);
} else {
objectData[this.name] = value;
}
});
return objectData;
};
The problem is that my serialization does not take into account cyclic data structures. For example i have in my form
<form:input path="discipline.cnfpDisciplineCode" class="required" />
and this gets serialized as
{
...
discipline.cnfpDisciplineCode : someValue
...
}
Is there an elegant solution to serialize the form to make it look like
{
...
discipline :
{
cnfpDisciplineCode : someValue
}
...
}
Or do i have to implement the whole parsing algorithm myself?

...and extend this abstract test class for each implementation (which I am running with `@RunWith(Parameterized.class)`). I'm also passing some variables to test the implementation of the interface against into the abstract test class.
However, in actuality, some interfaces return objects that are implementations of other interfaces, and I would like to be able to test this implementation using the abstract contract class for that interface (...and against the relevant variables).
At the moment, I'm adding the following to the abstract test classes:

I've seen stuff about the `@RunWith(Suite.class)` annotation, but that seems to be about running multiple test classes from a single test class, and doesn't allow you to pass variables into the different test classes that are being run.

I want to use the option "Import > Git" in eclipse to import the Android Projects. And later use "Team > Pull" to obtain the latest versions of these projects. Is that possible? How?
My two principal problems are:
- The android project there is not in the root of the repository, and
- there is not .project file.

Everything more or less works, but I wanted to apply some custom formatting to some of the columns. I figured out how to get a list of the columns by just taking the first row and casting it like so:
var columns = Model.Comparisons.Select(x => x).FirstOrDefault() as IDictionary<string, object>;
Next I decided to create my List<WebGridColumn> by looping over the "columns", which works as long as I reference the dynamic fields in the "format:" clause by their dynamic field name directly for example:
foreach (var c in columns)
{
switch (c.Key)
{
case "Cost":
cols.Add(grid.Column(
columnName: c.Key,
header: c.Key,
format: (item) => Convert.ToDecimal(item.Cost).ToString("C")));
break;
default:
cols.Add(grid.Column(columnName: c.Key, header: c.Key, format: item => item[c.Key]));
break;
}
}
The "default" does not dynamically get the value of each record. I believe it has to do with the "item[c.Key]" vs item.Cost. The problem is I don't want to have to write different case for each field, primarily because I don't know them ahead of time as the data can change. There are about 6 fields that will always be present. I do know however the datatype, which is why I wanted to put a custom format on them. | mvc | webgrid | expandoobject | null | null | null | open | MVC 3 WebGrid with a dynamic source

I'd like to rewrite my application to use SQLite database feature.
Since I'm lazy, I'd like to use some kind of ORM.
So far I have found only two big ORM libraries:
- [ORMLite][1]
- [GreenDAO ORM][2]
- [DB4O][3]
My primary goal is to **raise performance on working with data as much as possible**
But I've found two possible issues with those libraries.
- ORMLite uses **annotations**, which is big **performance issue in pre-honeycomb** due to [this bug][4]
- GreenDAO is using some kind of code generator, and that would slow me down on development as I would have to write generator, and then use generated code. And I don't very like this idea.
- DB4O is JPA, which I've always considered as slow and heavy on memory usage, therefore unsuitable for low-end devices (remember the Android API v7)
So my questions are:
1. **Should I use ORM/JPA layer in Android application?**
2. **If so, what library would you recommend me to use?** (and please add some arguments too)

We are automating our UI testing by using Selenium Web Driver (v2.24.1), and it works like a dream with the exception on IE9.
We are doing part of client side functionality by hiding/showing UI controls via addClass and removeClass jQuery methods. addClass and removeClass jquery methods append (or remove) classes from DOM. This way, we can do Selenium DOM iteration looking for those changes in order to trigger actions...
Our problem is that those DOM changes are not reflected in IE9 – e.g. functionally everything is working correctly on IE, but the “dom is static”, thus Selenium cannot reckognize some panel is shown or hidden...
So, the question:
1) Is there a way to reflect the addClass and removeClass in IE9 in a dynamic manner?
2) Should we possibly monitor/capture changes in a different way? (Possibly assigning some kind of event listeners on the components that are causing us problem?)
Hope this question is not too vague – this is not an issue with one particular component, but I think it is more down to the way we are trying to use Selenium in a generic way across multiple products...

===
Hi – apologies for a bot of a generic question... We are automating our UI testing by using Selenium Web Driver (v2.24.1), and it works like a dream with the exception on IE9.
We are doing part of client side functionality by hiding/showing UI controls via addClass and removeClass jQuery methods. addClass and removeClass jquery methods append (or remove) classes from DOM. This way, we can do Selenium DOM iteration looking for those changes in order to trigger actions...
Our problem is that those DOM changes are not reflected in IE9 – e.g. functionally everything is working correctly on IE, but the “dom is static”, thus Selenium cannot reckognize some panel is shown or hidden...
So, the question:
1) Is there a way to reflect the addClass and removeClass in IE9 in a dynamic manner?
2) Should we possibly monitor/capture changes in a different way? (Possibly assigning some kind of event listeners on the components that are causing us problem?)
Hope this question is not too vague – this is not an issue with one particular component, but I think it is more down to the way we are trying to use Selenium in a generic way across multiple products...

Scalaz likely already provides something like this, but am curious to know how, without a separate library, one can concisely handle the following simple case:
I need to check if user session exists, both actual user and admin logged-in-as-user scenarios, the latter taking precedence over the former; if neither conditions exists, show login screen.
The actual user session check looks like:
request.session.get(Security.username) map { id=>
f(Success(id.toInt, request))
} getOrElse( onFail(request) ) // onFail = show login
and I need to add in the admin impersonating user case:
request.session.get(Security.impersonate) map { id=>
f(Success(id.toInt, request))
} getOrElse( onFail(request) )
I could getOrElse it all together but would prefer to clean things up a bit, the operation is the same regardless of user or admin-as-user cases.

Hey, this is my first time attempting to build an app with SRP in mind and really trying to use tests to drive the code for the site, rather than starting with my data architecture (AR) and then building the app to fit.
But... I'm running into problems... I've subscribed to and watched a lot of Destroy All Software screencasts and in theory I like what he preaches but I'm having trouble making it work in practice.
**Problem at hand**
So I know the main feature of my app will be to search profiles based on location. So I write a simple cucumber feature for that (purposely leaving off routes/controllers/etc for the time being to simplify the task at hand).
search.feature:
Feature: Search for profiles
Scenario: By zipcode
When I search for 90210
Then I will see profiles near 90210
search_steps.rb:
When /^I search for 90210$/ do
@profiles = ProfileSearch.new.near_location(90210).all
end
Then /^I will see profiles near 90210$/ do
pending # express the regexp above with the code you wish you had
end
No problems... now on to specs.
profile_search_spec.rb:
require_relative '../../app/services/profile_search'
describe ProfileSearch do
it "finds nearby profiles"
it "does not find far away profiles"
end
profile_search.rb:
class ProfileSearch
end
So I've used a ProfileSearch class for a few reasons.
1. It seems like the right thing to do to move as much business logic as possible outside of AR (SRP).
2. POROs make for faster tests (no loading rails)
3. I plan to use ElasticSearch or Solr in the near future and would like for the interface to remain the same.
Now, I'm not really sure what to do next. ProfileSearch obviously depends on the Profile model, and I'm quite certain that this will be AR.
So the question is do I start spec'ing out and building Profile and just start loading rails in my tests. This seems like the easiest option but something about it seems wrong. I feel like I would be desiging and building behaviour that my app hasn't specifically called for yet. I would have to think about fields and relations and storage, etc. All of which my app currently shouldn't care about.
Or should I use stubs/mocks for all calls to Profile in my ProfileSearch spec and make sure the correct methods are being called. This also seems wrong because I'm not really testing the behaviour then, and the test would have to be rewritten when switching to Solr/Elastic even though the same behaviour would be expected.
Or maybe I should actually create a working Profile model that doesn't use AR for the time being but responds correctly to all the right methods as Uncle Bob demonstrated when building his wiki thing. This seems like it might be the best approach theoretically but knowing I will be using AR in the future it also seems quite redundant.
Or... f*ck it and throw everything in the AR model :\
There are so many patterns, principles, and best practices floating around in my head I don't know wtf to do.

I am able to the get the file size. Then I want to set the content headers so that the browser knows the total size and thus knows how to proportion the seek bar.
Here I set the total size header:
string bytes = Convert.ToString( fInfo.Length );
Response.AddHeader("Content-Length", bytes );
Response.AddHeader("Content-Range", "bytes 0-" + bytes + "/" + bytes);
Resulting in:
Content-Length: 1389363
Content-Type: video/ogg
Content-Range: bytes 0-1389363/1389364
I downloaded the resulting file and confirmed that the bytes match. Works fine in Firefox, all wacky in chrome. **In chrome it plays to the end, but does not move the seek bar and then shows negative infinity in the current time when it reaches the end. ALSO I cannot scrub the video at all, presumably because it has an invalid duration.**
playing the same file directly in chrome works properly, so maybe it's some content header that chrome wants that firefox don't give a s#%t about?
Any ideas? Wrong length unit? built-in server side g-zip encoding interfering?

byte[] buffer = new byte[4096];

I have installed the Java Cryptography Extensions (JCE) for the 1.4 VM.
What could be the source of that problem?

To realize this I have an base interface `IPeristenceService` that defines all methods to access data inside the persistence tier. The interface could look something like this:
public interface IPersistence
{
TData GetData<TData, TKey>(TKey Key);
}
So the persistence service cannot create instances of objects that are only defined by their interfaces, so it is a good decision to restrict the implementation of the `GetData`-method:
public interface IPersistence
{
TData GetData<TData, TKey>(TKey Key) where TData : class, new();
}
This is pretty straightforward, because developers who are implementing this interface will not be able to compile their code when they try to return an interface pointer. The data inside the persistence layer needs to be represented by implemented objects, not by interfaces!
Now assume we are creating an persistence service, that persists data inside an relational database, represented by entities. All entities are inheriting from one base interface: `IEntity`. Passing non-entity objects must fail, because the persistence service can only persist entities. So we need to validate if the passed object instance inherits from `IEntity`. Using the where-notation this would be possible during compile-time, but simply implementing an interface like this:
public class DbPersistence : IPersistence
{
public TData IPersistence.GetData<TData, TKey>(TKey Key)
where TData : IEntity, class, new();
{
// fancy data access code
}
}
does not work, does it?!
Is there any way to realize what I am trying to do?
Thank you in advance :-) | c# | oop | inheritance | null | null | null | open | C# - change "where" restriction through inheritance

Why this permission issue occurs?
The following code works perfect when I call the service from the same app:
Intent intent = new Intent(this, DownloadService.class);
// Create a new Messenger for the communication back
Messenger messenger = new Messenger(handler);
intent.putExtra("MESSENGER", messenger);
intent.setData(Uri.parse("http://www.vogella.com/index.html"));
intent.putExtra("urlpath", "http://www.vogella.com/index.html");
startService(intent);

I used NSString with contents of URL to see how xCode is seeing the string and instead of a degree symbol I am getting wht I thiink is an elipsis ∞ symbol. When viewed in a browser the same string is a degree symbol.

I have created a method which draws all the controls to the panel, but its draws them based on the order which I have listed them, which means PictureBox1 will always be *behind* all the other pictureboxes. Example:
e.Graphics.DrawImage(PictureBox1.BackgroundImage, new Rectangle(PictureBox1.Location, PictureBox1.Size));
e.Graphics.DrawImage(PictureBox2.BackgroundImage, new Rectangle(PictureBox2.Location, PictureBox2.Size));
it draws PictureBox1 **first**, then PictureBox2 **second**., then PictureBox3 **third** etc..
Now when I push a button when focus is on picturebox2 I would like the DrawImage order to be changed so that PictureBox2 is drawn last.
I'm sure one of you has a great solution to this, I would like to listen to any suggestions you may have.

I work with Maya a lot, and one of its commands (listConnections) returns a list of alternating values.

for destination, source in cmds.listConnections():

You could, of course just iterate every other item in the list using [::2] and enumerate and source would be the index+1, but then you have to add in extra checks for odd numbered lists and stuff.
The closest thing I have come up with so far is:
from itertools import izip
connections = cmds.listConnections()
for destination, source in izip(connections[::2], connections[1::2]):
